My quick answer to the question "what is different with JIT, kanban, and lean production?" in facebook. (http://www.facebook.com/vithayas)
JIT is the ideal characteristics of production system, meaning no waste, no inventory, best utilization of machines and resources. In the past people didn't know what to call, they just picked the name "Just'in-Time". Actually, it is best logistics perspective of the system.
Later, Toyota wa successful in implementing JIT by learning from Ford and others western ideas. And also w/ leadership of Toyota's leaders, they included the ideas of Jidoka. Thus u can see the main 2 pillars of TPS (Toyota Production System) house, as JIT and Jidoka.
Kanban is a tool to communicate b/w processes to pull the materials to next operation in the manner of JIT. So JIT is not kanban, but TPS has a characteristic of JIT.
TPS is more than JIT. TPS starts w/ philosophy of company, people, process and technology. They're all integrated into the system that has characteristics of JIT.
In 1990, Womack and Jones had researched in what made Japanese car manufactures successful in north america market. They found that TPS is the core concept of operations for Toyota Motors. They tried to emulate the TPS concept to be genera...lized in different context. So they named it as Lean Production.
Actually, lean production is an application of TPS concept in other manufacturing environment other than Toyota. It means that we have to understand what Toyota think, not what Toyota do. If we can understand the thinking behind TPS, then we know Lean and are able to apply in any business environment.
